The Addition Working Charts is a Mathematics Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
The Addition Working Charts offer systematic practice of addition facts through hands-on manipulation of wooden number tiles on laminated control charts. This comprehensive set includes multiple chart formats and a complete set of number tiles stored in a dedicated wooden box, allowing children to work independently through addition combinations up to 18. The blue-headed control charts provide visual organization and self-correction opportunities essential to the Montessori mathematics curriculum.
“Children display a universal love of mathematics, which is par excellence the science of precision, order, and intelligence.”— Maria MontessoriThe Discovery of the Child
“The greatest sign of success for a teacher is to be able to say, 'The children are now working as if I did not exist.'”
— Maria Montessori, The Absorbent Mind
The Addition Working Charts transform abstract numerical relationships into concrete experiences through systematic tile placement on laminated control surfaces. Each wooden number tile represents a quantity that children physically manipulate, building neural pathways between hand movement and mathematical understanding. The blue-headed control charts create visual organization that mirrors the logical structure of addition itself, while the multiple chart formats accommodate different learning stages within the same material. The dedicated wooden storage box teaches mathematical order—each tile has its place, just as each number has its position in the decimal system. By working through addition combinations up to 18, children discover patterns and relationships independently. The laminated surfaces allow repeated practice without wear, essential for the extensive repetition mathematics requires. This systematic approach to addition facts emerges from Montessori's observation that children need concrete manipulation before abstract calculation, and that mathematical precision develops through ordered, sequential work with beautiful, purposeful materials.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Begin with the first equation on the chart (1+1). Select the corresponding answer tile from the box
Place the wooden tile in the designated space on the laminated chart
Continue working systematically through each equation row by row
When complete, check work using the control chart with blue headers
Return tiles to their designated compartments in the wooden storage box
Every material is carefully selected for durability, safety, and authentic Montessori experience.
Durable lamination protects the charts from repeated use while maintaining clarity of the mathematical grids
Smooth wooden number tiles provide tactile feedback essential for kinesthetic learning of abstract concepts
Each material supports multiple areas of child development simultaneously.
Systematic practice helps children memorize addition facts through repetitive, hands-on work with concrete materials.
Visual organization of charts reveals mathematical patterns and relationships between numbers.
Self-correcting materials allow children to work autonomously and check their own work.
Bridges concrete manipulation of tiles to abstract understanding of addition operations.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Present one chart format at a time, allowing mastery before introducing variations”
Observe which addition facts challenge each child and note patterns for targeted practice
Store completed work for portfolio documentation of mathematical progress
Rotate available charts weekly to maintain engagement while ensuring repetition
Everything you need to know about this material.
The set includes multiple laminated control charts with blue headers, a complete set of wooden number tiles for working through addition combinations, and a dedicated wooden storage box to keep all materials organized and accessible.
The blue-headed control charts provide visual organization and built-in control of error. Children place number tiles on the charts to complete addition equations, and can check their work against the control patterns, allowing independent practice and self-correction.
Children can systematically work through all addition combinations with sums up to 18, providing comprehensive coverage of basic addition facts essential for mathematical development in the 3-6 age range.
Different chart formats allow for varied practice approaches and progressive difficulty levels, enabling children to work with addition facts in multiple ways - from simple combinations to more complex patterns, supporting thorough understanding and memorization.
The materials are designed for autonomous use - children can select tiles, work through equations at their own pace, and verify answers using the control charts without adult intervention, fostering independence and confidence in mathematical work.
